ing as indicated at 21 in Fig. 9.

In the -modified form of the invention illustrated in Figs. 6, 7, 8 and9 the bore of the tubular member 10 at the writing end thereof has theform of an elongated openticular form of opening at the writing end ofthe tubular member 10 will enable certain desired shading to be efiectedduring the operation of lettering. As the result of the and thisrelative position of the core is, de

termined by providing same with a laterally projecting .pin 22 whichseats in a recess 23 in the tubular member when the core and tubularmember are disposed in proper assembled relation. In other respects theform of pen illustrated in 6, 7, 8 and 9 is similar to that illustratedin Figs. 1, 2, 3, 4 and '5 both as to structure and operation.

It will be noted that the core 16 is provided with fiatfaces 22' at eachside of the openin 17 so as to not engage the interior wall 0 thetubular member 10 during the This parinsertion of the core into thetubular memfaces 22"alsoserve to orm an air inlet and eflect an even andfree flow of the ink through the .writing point.

What is claimed is:

1. A pen formed of a tubular member, one end of which constitutes awriting point and an ink carrying core removably mounted in said member,said core comprising an integral head having a transverse openingtherethrough for receiving and holding ink, and further provided withlongitudinal grooves on its side face communicating with said transverseopening through the end of the core adjacent the writing point.

2. A pen formed of a tubular member, one end of which constitutes awriting point an an ink carryingcore removably mount ed in said member,said core comprising an integral head having a transverse openingtheret-hrough for receiving and holding ink,

and further having flat side portions at the terminals of said openings,and means for conveying ink from the opening to the writing point. 1

In testimony whereof, I aflix my signature in presence of two witnesses.
